Libby Dam Legacy: Ode to the Past

Libby Dam History

Libby Dam in northwest Montana was constructed in response to annual spring flooding events

cascading down from the Rocky Mountains that caused death and destruction to communities in the US and Canada located along the length of the Kootenai and Columbia River watersheds.     

  • With Department of Defense contractors, the U.S. Army Corps of Engineers began construction in 1966 and the dam was dedicated Aug. 24, 1975. 

Employing over 2,000 workers at the peak of construction, the Army Corps built three new schools, additions to existing schools and the Libby Airport. The Army Corps also moved the town of Rexford to higher ground, relocated Highway 37 and the Great Northern Railroad Line which includes a 7-mile long tunnel through Elk Mountain that trains still use today. 

A forest development road was built on the west side of the reservoir, and the Koocanusa Bridge - Montana’s longest and highest bridge - was built to provide access across the reservoir. 

There are many stories still being told by the families of the people who built the dam, and people whose lives were changed by the construction of this massive dam.

Libby Dam 1975-2025

Soaring 422 feet tall, Libby Dam holds back the waters of the Kootenai River to form the 90-mile-long Lake Koocanusa reservoir, 42 miles of which are is in Canada.  Libby Dam maintains a delicate, daily balancing act between providing protection from floods, producing hydroelectric power, and managing natural and cultural resources and recreation, while contributing to irrigation and navigation operations downstream.   

Visit the Libby Dam Visitor Center between June, July, August and part of September, and learn more about Libby Dam’s history, current operations and future plans or visit Libby Dam’s public webpage: https://www.nws.usace.army.mil/Missions/Civil-Works/Locks-and-Dams/Libby-Dam/

Libby Dam 50th Commemoration Memories

Meet Phil Cole: Libby Dam's First Resident Engineer

Excerpt of an article written by Ray Aarstad on Phil Cole: 

"Mr. Cole’s job entailed more than overseeing every facet of the construction of the multiple projects that were going on, although the bulk of his time was dedicated solely to that purpose. A portion of that time, however, was set aside to keep the public aware of what was going on in regards to construction on the dam and the impact on the community. Involvement in the Chamber of Commerce and the Libby Rotary Club were important because they gave him a venue in which to keep local community leaders and businessmen abreast of Corps activities. This was something that he did on his own initiative to keep community awareness at a high level. At these meetings he could discuss projected employment for the coming year and alert community leaders to what steps they needed to take to adjust to the influx of workers and their families. One subject that was reoccurring was the impact on the public school system. Money and buildings were needed to accommodate the rapidly expanding student body and by alerting community leaders ahead of time, the call could be sent out to bring in more teachers, secretaries, librarians and aids as needed.

These duties were in addition to the more traditional ones that the project construction dictated. Each contractor had a U.S. Army Corps of Engineers group that worked with him on a particular contract. These individuals insured that the contractor adhered to payment and labor practices that were in step with Corps policy. Likewise, each contractor had a limited period of time in which to complete the project they were working on. If extensions were necessary due to extenuating circumstances they could be granted but that was rarely the case. There were approximately one hundred and thirty four contracts that related to the construction of Libby Dam and its co-projects, each involving thousands of man-hours to be completed, inspected and approved.
 
The resident engineer for a project of this magnitude was hand picked by the district. He had to be a man who could handle the daily problems that are endemic to dam building and since all dams are different there was no handbook to be consulted to solve the problems he would face. Also, an individual chosen for this duty had to be a person who could manage the broad range of responsibilities that went along with the job; part public relations, part dictator, part benevolent father figure, the resident engineer’s power and use of it made him an omnipotent figure during the construction phase. Chosen for this position of immense responsibility was Mr. Phil Cole, a quiet spoken man whose acumen as an engineer was matched by his savvy for handling people. He was without doubt the right man for the job.
 
Mr. Cole arrived in Libby in December 1965 and his first impression was not favorable. The tiny U.S. Forest Service airstrip was considered unserviceable so travel to and from Seattle was via passenger train on the Great Northern. Three years later the problem of a serviceable airstrip was solved when construction was completed on a new airport. Mr. Cole’s staff consisted of himself and three other Corps employees and at the same time he faced community residents who were suspicious of the project and those who welcomed it with open arms. Undaunted, he went to work rising sometimes at night to go to the project site to check on progress. His work ethic was straightforward and simple; he went to work and worked until there wasn’t anything left to do. This dedication made for long days and short nights on a project that would take years to complete.”

Part of Phil's duties involved keeping community groups updated on the project. Mildred and Karen donated a 24-inch model of a bark canoe the Creston Board of Trade presented to Phil, in 1958.

Taking Care of Business: Now and Into The Future

Current Projects 

Libby Dam has had five generating units since 1985, but did you know that its powerhouse was originally designed for eight generators? U.S. Army Corps of Engineers recently awarded a contract to install a sixth unit, which will add flexibility to plant operations and improve the dam's overall electrical reliability.

A project to improve the project's intake crane began the week of April 7, 2025. The $13.6 million replacement project, which features an additional 30% loading capacity, is designed to be aesthetically similar to the original crane, to reflect the architectural influence of Paul Thiry (1904-1993), who consulted for the project. The crane intake improvement project is expected to be completed July 22, 2025. 

Future Projects 

Transformers are robust machines with very few moving parts. That said, even transformers need a little "TLC" every now and then. Generator Step-Up Transformer #1 is scheduled for a rehab around summer 2025.  The rehabilitation will update protection devices and bushings as well as replace valves and gaskets. 

Our GSU transformers are located between the powerhouse and the dam and can be seen easily from above.  Take a look while on a tour or from home using your favorite map website. GSU #1 is one of four GSU transformers at Libby Dam and is the one closest to the visitor center or furthest to the west.

Libby Heritage Museum 

 The U.S. Army Corps of Engineers is partnering with Libby Heritage Museum, through paired displays of memorabilia and photos of Libby Dam's construction and its 1975 dedication ceremony, to encourage visitors to visit and learn more about both facilities.  

During the dam's construction, contractors for the U.S. Army Corps of Engineers, including Morrison-Knutson and sub-contractors, brought more than 2,000 employees to help build the dam over the course of about 10 years. During that time, the U.S. Army Corps of Engineers made many official additions to the area, including schools, an airfield, a bridge and a railroad tunnel.  While many of these employees moved on to the next dam or construction project, some remained in Libby and became members of its community. 

Libby Heritage Museum's unique 12-sided log building built nearly 50 years ago in Neotraditional Rustic architectural style, would not exist if it not for three U.S. Army Corps of Engineers, Libby Dam employees.  

  • Structural Engineer Floyd Lucas, who volunteered to design the museum building and draw the blueprints. 
  • Electrical Engineer John Davidson, who served as volunteer building Construction Chair, completed the electrical wiring and poured the cement flooring.  Now in his 90's, Mr. Davidson still lives in Libby and volunteers on occasion at the Museum, and 
  • Claude Huckins, who worked with local logger Dan Emerson to stack the 800-900 local larch and lodgepole logs, according to the blueprints. 

The Libby History Museum is listed on the National Register of Historic Places and tells the story of community volunteerism at its best. The building has achieved exceptional historical and cultural importance to the local Libby community, to future generations, and to the preservation, study and future research regarding the history of northwestern Montana.
